FAQ

Does this include data egress or storage?

No. It isolates compute rate differences only. Add networking or storage to your budget separately.

Can I use this for committed use discounts?

Yes. Enter the committed hourly rate in the spot field to see savings versus published on-demand pricing.

What if on-demand is cheaper than spot?

The calculator will show negative savings and a negative savings rate, indicating spot pricing is higher in that scenario.
